Answer:
24 students
Step-by-step explanation:
So we started with 32 cups of juice.
Kahled drunk 2 cups so (32-2)=30 cups is left.
If x represents the number of students he receive juice and each student gets the same amount of juice which is 1.25 cups, then we have the equation
1.25x=30 to solve for x.
Divide both sides by 1.25:
x=30/1.25
x=24
24 students receive juice
Answer:
81 square inches.
Step-by-step explanation:
Draw a diagram to represent what you know.
You don't know the values of the lengths so represent them algebraically.
You know the perimeter is 45 inches and that the perimeter is calculated by the sum of all of the sides of a shape.
You can rearrange to find the value of a side you've denoted as some unknown variable.
The area is given by the product of the sides. Express this algebraically and then input the value you found.
Answer:
-69/200
Step-by-step explanation:
-0.345 is in decimal form.
In Fractional form (p/q)
=-345/1000
To simplify, divide the numerator and the denominator by the G.C.D(Greatest Common Divisor) of p and q.
In this case,G.C.D of 345 and 1000 is 5.
Simplified form=-69/200 [ANS]
Answer:
That would be sina.
Step-by-step explanation:
sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
Adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
Answer:
12.60
Step-by-step explanation:
To find the tip, take the amount of the bill and multiply by 30%
42 * 30%
Change to decimal form
